 *  Some things to keep in mind:                                        
 *  - These functions only work on C function names.  Other languages may
 *    have name mangling and intrinsic language support that varies from
 *    compiler to compiler.
 *  - Make sure you declare your function pointers with the same calling
 *    convention as the actual library function.  Your code will crash
 *    mysteriously if you do not do this.
 *  - Avoid namespace collisions.  If you load a symbol from the library,
 *    it is not defined whether or not it goes into the global symbol
 *    namespace for the application.  If it does and it conflicts with
 *    symbols in your code or other shared libraries, you will not get
 *    the results you expect. :)
